o O ( Oooo and this seems to be the 5th guy from Rolla - any asp/db coders in here? )

Anyways, it's interesting to see that he found equations to calculate stuff like this: "It can model insect populations that are continuous while in season, die out in winter, while their eggs are incubating or dormant, and then hatch in a new season, giving rise to a non-overlapping population."

Very intersting... I just hope they don't make Dynamic Calc a requirement for my Math minor! I'm almost done with it. Hehe.

Am I understanding this correct but all it is doing is taking discrete calculus and non-discrete calculus and combining them? I don't see how time scales would affect a discrete function enough to be applied to non-discrete calculus, or am I not understanding the meaning of time scales?

Big deal. So he can integrate or differentiate across discontinuities. I can prove there is no justice in the world. He did all this work for a tiny fraction of the money an 18-year-old girl got today for being born to the right parents.

BTW, I got two more slide rules yesterday, a Pickett N4-ES and a K&E 4081-3. I now own 13 slide rules. Oops! my nerd side is showing. Ahem! I also got some new saddlebags for my Harley Davidson Superglide.
